Don't sweat it if you forgot to pull your holiday ham out of the freezer, or it simply hasn't thawed as quickly as you expected. It's perfectly safe to cook a frozen ham. Just know that it takes about 50 percent longer to cook a fully frozen ham. In the case of a ham that is fully cooked, you are really only warming it up, but it takes significantly longer to do this from its frozen temperature of 0 F.

Cooking Temperatures

Preheat your oven to 325 F.  When the oven is warmed to the correct temperature, place the ham in the oven, uncovered, and cook it until its internal temperature meets or exceeds the following:

Cooked Ham (vacuum-packed at the plant) — 140 F
Cooked Ham (repackaged by you or someone else) — 165  F
Uncooked Ham (labeled fresh, cook-before-eating or uncured)  — 145 F
